Well of course I can't, 9's=cage....after I got her running/hooking good on the street, engine is back far as possible without cuting the firewall, alu heads, MT sportsmens Pros running 6psi, and played with the preload till I only spun 1-2 foot I went to a test and tune at the local track, they ask how fast it was, I said I did'nt know but guessed 13's I really was'nt sure but was guessing mid-high 10's, well 9.42 sec later at 140 mph they told me not to come back without a cage, I still aint been back, not going to put a cage in her, it's a street car after all, oh yeah the wheelie bars are welded on and NOT for show, don't get serious without them for your own saftey.
